How many degrees does the femoral neck typically project anteriorly?

• A. 10° to 15°
• B. 15° to 20°
• C. 20° to 25°
• D. 25° to 30°

Answer: (B)

The femoral neck typically projects anteriorly at an angle of about 15° to 20°. This angle is important in radiographic imaging and helps in positioning for optimal visualization of the hip joint and surrounding structures. The anterior projection of the femoral neck allows clinicians to assess the hip joint and femoral head accurately, which is crucial in diagnosing fractures, arthritis, or other pathologies related to the hip.

Understanding this anatomical feature is particularly vital for radiographers as they need to position patients correctly to avoid distortion in X-ray images. A projection that is too shallow or too steep can compromise the quality of the images obtained. Knowledge of the normal angulation assists technologists in making informed decisions about patient positioning and the selection of appropriate imaging techniques.
